Convergence

A point of your choice becomes the epicenter of a great gravitational pull, that converges any matter within a 20 ft. radius to the singularity.

Any creature within range must make a DEX saving throw with disadvantage. On a failure, the creature gets tossed towards the center, taking 8d8 force damage, 3d8 bludgeoning damage, and and additional 2d8 bludgeoning damage for each other creature who fails. On a successful throw, the creature takes half force damage, and doesn't get tossed.
